The household operations system that runs on the accounts and calendars you already have.
mdash is the household operations system that runs on the accounts, calendars and devices you already have. No new email address. No hardware. No setup weekend. Everyone signs in as themselves, connects their own calendar, and the day everybody is actually having shows up on one screen.
Google Calendar and any published ICS feed. mdash never writes an event, never moves one, and never deletes one. Disconnecting revokes the grant with Google, not just here.
One of Oura’s eight scopes — sleep, activity and readiness for the day. Not the continuous heart-rate series, which is the most sensitive thing a ring exposes and which nothing here reads.
Nothing to reuse, nothing to leak, nothing for a household to share badly. Connecting a calendar is a separate decision from signing in, and either can be undone without the other.
